The present ram 15 which is mounted for vertical movement over the bed plate 2 car ries a plunger member 16, which upon a downward movement thereof coacts at its lower end with a work piece a, held by the bars 12 over the die openings 10, and forces the work piece down between the sets of dies 9, its ends being broached or trimmed during such downward movements by reason of the coaction of the serrated die surfaces therewith.-

It isevident that the ends of a work piece project at each end a greater or less extent into the openings 10 of the respec tive dies, so that the dies have a shearing action thereon as the work piece is forced downward therebetween. When the Work piece has passed below the dies 9, it drops through registering openings 17 and 18 in the bolster plate 2 and bed 1 into any suitable receptacle provided therefor.

The dropping of work pieces from the magazine 11 into the guide way formed by the bars 12, and the successive delivery of work ieces through said guide way into operatlve position over the die openings 10 is controlled by a slide 19, which is mounted for reciprocatory movements between the guide bars 12. This slide is of suitable length to close the loWer end of the magazine 11, exceptwhen the slide is in complete retracted osition, thus permitting a work pieceto rop into the guide way only in advance of said slide and when in retracted position.

The slide 19 has toggle link connection 20 with a shaft 21, journaled in suitable bearings 22 on top of the bolster plate 2, and carries a inion 23 in mesh with the teeth of a vertically reciprocating rack-bar 24. This rack-bar has its upper end projected loosely through an arm 25 extended horizontally from the lower end portion of the ram 15, and is provided above and below said arm with stop collars 26 and 27, respectively, which are spaced to permit a limited movement of the arm 25 with respect to the rack-bar. The arm 25 when moved upward with the ram 15, and near its upper position, is intended to engage the stop collar 26, which is suitably positioned for such purpose, and to effect a raising of the rackar 24 during the balance of the upward movement of the ram, thereby effecting a forward movement of the slide 19 to place a workpiece a, which is disposed in the guide Way in advance thereof, in operative position over the die openings 10 and below the plunger 16. Upon the next downward movement of the ram 15, the-rackbar 24 lowers therewith by gravity and causes a retraction of the slide 19 out of register with the plunger 16. When the plun er 16 is near the limit of its downwar stroke, the arm 25 engages thelower stop collar '27 and efi'ects a positive lowering f the rack-bar and a complete retraction of the slide 19 to permit thelowermost work piece a in the magazine 11 to enter the guide way in advance of the slide. Upon the next upward movement of the plunger, the rack-bar 24: is raised and the slide 19 perated to force the work piece 11, disposed in advance thereof, into holding position between the flexible ends of the bars 12 and in register with the plunger 16 and die'openings 10.

It is evident that I have provided a simple and efiicient mechanism which is operable to successively feed work pieces into operative positionvabove the breaching or trim-- ming die and to force the work pieces down between the dies to simultaneously trim or broach the ends thereof.

I wish it understood that my invention is not limited to any specific construction, or rangement, or form f the parts, as the present embodment thereof is merely illustrative of one formof the invention and is capable of numerous modifications without departing from the spirit of the claims.

Having thus described my invention, what I claim is new and desire to secure by Letters Patentis2- 1. In a machine of the class described, two transversely spaced dies, each die forming a V-shaped opening having cut-ting walls, and means for forcing a. work piece between said dies with its ends projecting in the openings thereof to effecti a simultaneous trimming of such ends.

2. In a machine of the class described, two transversely spaced dies, each die form ing a V-shaped opening having cutting walls, and means for forcing a work piece between said dies with its ends projecting in.-the openings thereof to effect a. simultaneous trimming of both :ends, and means periodically operable to automatically move work pieces into operative relation to said dies.

3. In a machine of the class described, two transversely spaced V-shaped dies,

.means for forcing a work. piece between said dies to cause the dies to simultaneously trim the'ends of the work piece, and means operable to periodically deliver a work piece into position to be forced between the dies by said surface means, said delivery means having parts which frictionally engage and yieldingly hold a'plunger andthe work piece in operative relation to said dies and first means. i

4; In a machine of the class described, die means 'having'transversely spaced dies vprovided with V-shaped. work trimming openings, a plunger reciprocally movable to force a work piece between saidspaoed operable-by movements of said plunger to, periodically deliver work pieces from said u magazine into position to be engaged by the plunger and forced between said die parts. 5.
